In front of a sold-out crowd at the DoubleTree Hotel in Sacramento, CA Global Boxing Organization light heavyweight champion Ryan “The Rhino” Bourland (12-1 5KOs) of Vallejo, CA successful defended his title against Alfredo Contreras (13-20-2 5KOs).

Bourland used improved boxing technique as he recently began working with Mario L’esperance, a famed boxer as well boxing coach from Vallejo, CA. Bourland was able to withstand tricky movement, taunts and subtle movement to withstand Contreras, who is currently in camp sparring Julio Cesar Chavez Jr.

The co-main event saw Mike Guy (9-2-1 5KOs) stop former GBO light heavyweight title contender Gilberto Rubio (7-5 5KOs) when a third round right hook forced the referee to intervene as Rubio was unresponsive.

In other action, Turlock, CA cruiserweight Marco Delgato (2-0 2KOs) brutally knocked out Jerhed Fenderson (1-3) as he landed a brutally hook on the ropes at the end of the bell that rendered Fenderson unconscious while standing up. It was truly bizarre and something that I had never seen before.

Junior welterweight Luis Lizarraga (1-0 1KO) engaged in a fun action packed fight that might have had the Northern California round of the year as he stopped Phillip Percy (0-3) in the third round. Lizarraga at first struggled with Percy’s speed, but then overpowered him and broke him down with relentless punching attacks that had Percy staying on the ropes.

In the opening bout, Ignacio Zambrano (1-1) picked up his first professional win of his career as he earned a majority decision over hometown favorite Dyron Dorsey (0-3) in a fight in which Zambrano pushed the fight.
